Place the block on two round pencils and pull it uniformly.
Used to measure the force applied to the object. Wooden block: The primary object being moved.
Pull the block across different surfaces (e.g., glass vs. sandpaper) while keeping the weight constant.
You will notice that as the weight increases, the dynamometer reading increases proportionally. Calculation: The friction force is calculated as: Ffr=μ⋅Ncap F sub f r end-sub equals mu center dot cap N is the coefficient of friction and
